LOS ANGELES (Reuters) - Satellite TV provider EchoStar Communications Corp. (Nasdaq : DISH - news) and Viacom Inc. (NYSE : VIAB - news) have extended talks into next week on a deal that would include broadcast rights for CBS stations in major cities, including New York and Los Angeles, both sides said on Thursday.

EchoStar also said that while negotiations continued, it has asked the U.S. District Court in San Francisco to hold in abeyance a lawsuit it filed a day earlier.

EchoStar's suit seeks to block Viacom from withdrawing rebroadcast rights for its CBS-owned stations. The suit says Viacom has insisted that any deal for rights to its CBS affiliates must include arrangements for Viacom-owned cable networks such as a new offering, Nicktoons.
